The Dynasonics UFX ultrasonic flow meter is a handheld doppler flow meter. The Dynasonics UFX
ultrasonic flow meter utilizes advanced ultrasonic technology, providing accurate and reliable flow
velocity assessments in closed piping systems of 1/4" (6 mm) and higher.
The Dynasonics UFX ultrasonic flow meter employs a non-invasive, hand-held transducer which is
placed on the outside of the pipe. Within seconds, the large 0.7 inch (18 mm) LCD provides stable
readings in feet per second or meters per second. The Dynasonics UFX ultrasonic flow meter
operates on metal or plastic pipes containing liquids with greater than 100 ppm of 100 micron size
suspended solids or entrained gases. The Dynasonics UFX ultrasonic flow meter measures fluid
velocities from 0.3 to 30.0 FPS (0.10 to 9.00 MPS) with a 100:1 turndown ratio.
The easy-to-use Dynasonics UFX ultrasonic flow meter provides accurate flow readings on
applications such as dredging systems, crude oil, sludges, and waste slurries. Flow verification is
provided for many industrial and municipal applications.
Operating Principle
The Dynasonics UFX ultrasonic flow meter utilizes an advanced ultrasonic measuring technique,
providing accurate, non-invasive, fluid velocity assessments without opening the pipe. Utilizing two
piezoelectric crystals contained within one transducer, the Dynasonics UFX ultrasonic flow meter
transmits ultrasonic energy into the fluid stream and receives reflected energy off discontinuities
(suspended particles or entrained gases) within the moving liquid. Transformations that result from
the energy reflections are processed and converted to fluid velocity by the Dynasonics UFX
ultrasonic flow meter's sophisticated software algorithm. The processor also controls all operations
of the instrument from its ultra-efficient battery management circuitry to a proprietary FIR (Finite
Impulse Response) filtration program.
